Transfer Case

Just bought a 93 YJ, 4cyl, 5spd, 4x4. Traded a small pick up for it. It has a clunking sound when driving and I have narrowed it down to the transfer case. What it does is when driving and with it in gear, both 4-wheel and out, it makes a clunking sound that matches the turining of the drive shaft. I have changed the fluids, replaced all u-joints. With the front drive shaft removed you can grab the Yoke and turn it from side to side and you can here the clunking sound happening, the yoke moves about 2-3 inches and then if you turn it fast the opposite way you hear the clunk. I have not dropped the tranny and transfer case yet, has this happened to anyone and if so was it just a bearing or does the entire transfer case need to be rebuilt? The jeep has a 4 inch lift and a 3 inch body lift, I want to do this right. Thanks for your comments.

You can rebuild just the case. Im sure you already do but it is the perfect time to install a sye kit. If you dont feel comfortable doing this you could save money but pulling the case and taking it to a transmission shop. But rebuilding it will be a whole lot cheaper and sensible in my opinion.

Jeep moves when transfer case is in neutral

Have 2015 Jeep Wrangle Unlimited Freedom. In the manual #6 in the directions for prepping for towing, it says to put the automatic transmission into drive after the transfer case is in neutral to see if there is movement. Well, there IS movement... both in drive and reverse. How come? does that mean that the transfer case really is not in neutral? If so, what kind of damage am I doing to the car if I towed it that way? Please help!

Movement from being driven by the engine, correct? Not just rolling with gravity?
Sounds like it is not in neutral.
What procedure are you using for putting the transfer case in neutral?

DREDnot, no it is moving like rolling with gravity. There was no engine noise at all. We followed the directions in the manual. This is what we did, but in number 8 and 9b there was rolling:
1. Bring vehicle to complete stop
2. Press and hold brake pedal.
3. Shift automatic transmission into NEUTRAL
4. Turn the engine OFF
5. Shift the transfer case level into NEUTRAL.
6. Start the engine.
7. Shift the transmission into REVERSE
8. Release the brake pedal for 5 seconds to ensure no movement
9a. Shift the transmission into DRIVE.
9b. Release the brake pedal for 5 seconds to ensure no movement

Sorry I didn't respond back right away. I lost this post as it was for a 2015 JK in this old YJ thread.

I've not actually tried to put a JK into neutral so I'm not 100% sure how the procedure goes, but if you followed those instructions and it will roll with gravity you should be good.
They are assuming you are on a level surface.
Heres how I would say to prove to yourself that you are properly in neutral...Be somewhere level and safe. Do the shift into neutral procedure. With the engine running, shift into drive and you shouldn't move. Shift into reverse. Likewise , you shouldn't move. now put it in park. you should be able to get out and grab the tire and roll the jeep backward and forward. In park, engine on, in park engine off, no matter to should roll freely until you engage the parking brake . Now, you can follow the procedure to put the transfer case back in 2WD and it should now drive like normal.

If so, practice that neutral shift a few time to become fully familiar with it.
